Definitions

  • the present invention relates to the striking mechanisms of the hours, either by passing or by repetition type.
  • Such ringtones are well known to those skilled in the art. They allow to indicate the time of sound, by a succession of notes struck on stamps.
  • Such watches include a power source and a striking device and are, for example, described in the book entitled “Complicated watches” by Institut Lecoultre, Watchmaking Editions, Bienne, 1951.
  • the regulator comprises a recoil anchor cooperating with a ratchet wheel whose working conditions define the frequency of the ring.
  • the amplitude of the anchor is defined by an eccentric mounted to hard friction on the frame. The greater the amplitude, the lower the frequency of hits. The adjustment of the frequency is therefore at the end of the kinematic chain, on the member ensuring the stability of the frequency of the sound signal.
  • This adjustment is made by a watchmaker, during manufacture, and involves relatively delicate operations. If the wearer wants a slower or faster signal, or if other factors have led to a change in the signal frequency, then it is necessary to call in a specialist.
  • the object of the present invention is to overcome these disadvantages.
  • This object is achieved by virtue of the fact that the mechanism furthermore comprises a speed variator integrated in this wheel, and control means cooperating with the variable speed drive so as to allow the change of the driving speed of the device. of ringtone.
  • the drive controller can be integrated in the train between the power source and the speed controller as well as between the energy source and the buzzer.
  • variable speed drive comprises two kinematic chains.
  • control means comprise a movable member movable from one to the other of two stable positions and cooperating with a mobile of the train, moved to make active one or the other of these chains.
  • control means comprise a member coupled to the cage for moving it along the axis of the shaft.
  • the balls move radially, changing the ratio of speeds between the input wheel and the output wheel.
  • the present invention also relates to a striking watch movement equipped with a mechanism according to the invention, and a watch provided with such a movement.
  • This watch further comprises a box provided with a control member accessible from the outside and cooperating with the control means. In this way, the user can himself change the frequency of the ring, without having to open the box.
  • the barrel 12 includes ( figure 2 ) a drum 12a, a shaft 12b pivotally mounted on the frame and on which the drum 12a can rotate, and a spring 12c housed in the drum 12a and connected thereto by its outer end and the shaft by its inner end.
  • the shaft 12b carries, integral in rotation, a wheel 18 provided with wolf teeth.
  • a wheel 20 is mounted idle on the shaft 12b. It carries a spring pawl 22 engaged in the teeth of the wheel 18. It is provided with an external toothing 20a, forming the first wheel of the train 10 and intended to cooperate with the device 16, as will be explained later.
  • the variator 16 comprises a mobile 24 pivotally mounted on the frame and a rocker 26 integral with the shaft of the mobile 24 and can pass from one to the other of the two positions shown in FIGS. figures 1 and 3 .
  • Flip-flop 26 carries, in addition, two mobiles 28 and 30 each comprising a wheel and a pinion. These mobiles mesh permanently with their wheel with the mobile 24, while the pinions of the mobiles 28 and 30 mesh respectively with the wheel 20 as the lever 26 occupies the positions shown on the figures 1 and 3 .
  • the number of teeth that comprise the wheels of the mobiles 28 and 30 are different.
  • the wheel of the mobile 28 has twenty-four teeth, that of the mobile twenty-seven.
  • the ratio of gears between the configurations illustrated respectively on the figures 1 and 3 is 9/8.
  • the gear train 10 further comprises three mobiles 32, 34 and 36.
  • the pinion of the mobile 32 is driven by the wheel of the mobile 24, while the wheel of the mobile 36 drives the steering wheel 14.
  • the wheel 10 further comprises at least one not shown movable meshing with the wheel 20 and connected to a control device actuating a hammer for striking a stamp, at given times.
  • This part of the mechanism is well known to those skilled in the art. It is particularly described in the previously mentioned work.
  • the frame carries two abutment members 38 cooperating with a positioning member 40 to allow the lever 26 to occupy two stable positions, respectively illustrated in FIGS. figures 1 and 3 . Without the need to describe them further, those skilled in the art will be able to choose a suitable technical solution for producing the abutment elements and the positioning member.
  • the ringing has a duration of approximately 18 seconds when the gear train 28 is engaged with the wheel 20, and of 20 seconds, when it is gear wheel 30 which meshes with wheel 20, a gap of about two seconds between the two positions.
  • the Figures 4 to 6 represent another type of drive 42, ball bearing, to replace the drive 16 described above.
  • the mechanism of Figures 1 to 3 equipped with such a member corresponds to a second embodiment.
  • This drive is, as shown on the figure 5 , adjusted so that the steering wheel 14 has a maximum speed, and on the figure 4 a minimum speed.
  • the ring 62 is pivotally and slidably mounted on the cylindrical portions 46a and 48a. It angularly positions the balls 58 relative to each other, while allowing them to roll and move radially.
  • the conical surface 46b has a different apex angle than that of the conical surface 48b.
  • the apex angle defined by the surface 46b is smaller than that defined by the surface 48b.
  • the conical surfaces 46b, 48b and 60a respectively form first, second and third bearing surfaces for the balls 58.
  • the conditions of friction between the balls and the rolling surfaces must allow the balls to roll and not to slide on the surfaces 46b, 48b and 60a. In this way, the input wheel drives the output wheel. Due to the fact that the angles of the conical surfaces are different, the points of contact of the balls with the conical surfaces 46b and 48b are located at different distances from the axis AA, the raceways of these balls do not make the same length. This induces a speed differential between the input wheel and the output wheel, variable as a function of the position of the respective contact points of the balls with the conical surfaces 46b and 48b and also according to the apex angles defined by these surfaces.
  • the cage 60 By acting on the control member so that the steering wheel reaches its maximum speed and therefore, the duration of the ring is minimal, the cage 60 is moved in a direction parallel to the axis of the shaft 44, in the direction of the wheel 48. The wheel 48 is then pushed back, the spring 54 being compressed. This situation is illustrated in figure 5 . For a medium winding of the spring of the barrel, the ringing then has a duration of approximately 15 seconds.
  • the spring 54 By acting on the control member so that the steering wheel reaches its minimum speed and therefore, the duration of the ringing is maximum, the spring 54 makes the cylindrical portion 48a enter the cylindrical portion 46a, radially pushing the balls 58 to the outside, which increases the relationship between speed of the input wheel 48 and the output wheel 46.
  • This situation is illustrated in FIG. figure 4 .
  • the ringing For an average winding of the spring of the barrel, the ringing then has a duration of approximately 17 seconds, or 2 seconds more than in the position of the figure 5 .
  • control member can be stabilized at each position between the first and second extreme positions.
  • duration of the ringing sequence can be adjusted continuously between the maximum and minimum periods.
  • the control member may, for example, be an endless screw accessible from the inside of the watch case, in order to be able, by means of a screwdriver, to adjust the duration and frequency of the hour ringing. .
  • control member could also act on the position of one of the input or output wheels, an elastic member holding the conical surface of the cage 60 in contact with the balls.
  • the figure 7 illustrates schematically the manner in which the variable speed drive can be integrated into the gear train 10, in a watch equipped with a speed regulator, such as a flywheel type for example.
  • a speed regulator such as a flywheel type for example.
  • the energy source 12 the speed regulator 14 and the striking device 68 schematically represented by rectangles. They are interconnected by the gear train 10, which comprises three branches 10a, 10b and 10c, respectively connected to the power source 12, the speed regulator 14 and the striking device 68.
  • the speed variator 16 may be placed in one or the other of the three locations, identified 16a, 16b and 16c, or on the branch 10a, on the branch 10c and at the point of intersection of the three branches.
